I think the interesting thing about RGO box going for $45 is, with a bit of patience, one could find the actual eyepiece with box for maybe $20-$30 more. So the box is worth more than the eyepiece.

Your logic is flawed. Many, many things are worth more when "parted out" than when sold whole. How much does the EP alone sell for? I don't know as I've never looked at what they cost but it probably isn't less than what was paid for the box...
